7. Thickness or Gauge

Thickness of the matel sheets do not change during the perforation. Normally thickness is expressed in gauge, please see the picture. However, to avoid possible misunderstanding, we would suggest to express them in inches or millimeters.

8. Width and Length

The most common width and length are as follows:

1000mmX2000mm

1220mmX2400mm

1250mmX2500mm

1250mmX6000mm

1500mmX3000mm

1500mmX6000mm

However, we also manufacture other sheet sizes according to clients' requests.

9. Margins

Margins are the blank (un-perforated) area along the edges of the sheet. Normally the margin on the length are 20mm minimum, and margin along the width can be 0 minimum, or at clients' requests.
